all lines that are parallel to that one are related to: y = 3x
we need to adjust the given point (3,-2) so that it is the origin (0,0)
(3-3,-2+2)
but we need to do this to not only this one point, but ALL the points (x,y) on the line
(x-3,y+2) now we can use this in our related equation:
(y+2) = 3(x-3)
and simplify to your hearts content
